Compress files with tar at the shell prompt

For archiving files at the shell prompt, use the tar command as follows. The syntax is:
tar -cvf fileName.tar file1 file2 file3
tar -cvf fileName.tar dir1 dir2 dir3
tar -cvf fileName.tar file1 dir1
Where,

• c : Create a new archive
• v : Verbose output
• f : Use given archive file or device such as /dev/st0

Linux compress files with tar

For example, the c option requires creating the archive, the v option requests the verbose operation, and the f option takes an argument that sets the name of the archive to operate upon. The following command, written in the traditional style, instructs tar to store all files from the directory /home/vivek/Documents into the archive file docs.tar verbosely listing the files being archived:
$ tar -cvf docs.tar /home/vivek/Documents/
Sample outputs:

 tar: Removing leading `/' from member names
/home/vivek/Documents/

The following adds file named /etc/resolv.conf, /etc/hosts, and /home/vivek/project1 directory:
$ tar -cvf backup.tar /etc/resolv.conf /etc/hosts /home/vivek/project1

Compressing Files at the Shell Prompt

For compressing files you need to use the compression utilities:

1. bzip2 – tar.bz2 file
2. gzip – tar.gz file
3. zip – tar.zip file

To compress the tar file with gzip pass the -z option, run:
$ tar -cvzf docs.tar.gz /home/vivek/Documents/
To compress the tar file with bzip2 pass the -j option, run:
$ tar -cvjf docs.tar.bz2 /home/vivek/Documents/

To list the contents of a tar file, enter:

$ tar -tvf docs.tar
$ tar -tvzf docs.tar.gz
$ tar -tvjf docs.tar.bz2

To extract the contents of a tar file, enter:

$ tar -xvf docs.tar
$ tar -xvzf docs.tar.gz
$ tar -xvjf docs.tar.bz2
Where,

• t : List the contents of an archive
• x : Extract a tar archive
• z : Compress the tar file with gzip
• j : compress the tar file with bzip2
